Mj across 2 official records

Each registrar publishes its own list, so these figures are read down a row, never across one. A position in one country is not comparable with a position in another, and Namewise never combines them into a single ranking. The birth counts do not compare across rows either, for a different reason: England and Wales registers roughly thirty times as many births a year as Northern Ireland, so a larger total says which registrar recorded it as much as how widely the name was given.

What the record shows

Recorded by 2 registrars between 2010 and 2025, ranked in 10 years of that period.

Its highest recorded position is #343, first reached in 2023.

Its largest count from any one registrar is 11 births, registered in Republic of Ireland in 2023.

Its record falls into 4 separate stretches, with a longest absence of 3 years.

A second registrar first ranked it in 2015, and 5 years separate the first registrar to record it from the last.

Every figure here is counted from the seven official registrars Namewise holds. A position is only ever a place within the list that published it, and a record that thins or stops is a fact about what registrars printed — never about how many children received the name.

Absence from this list does not mean the name isn't genuinely meaningful or widely used — only that Namewise hasn't sourced and reviewed that content yet. Absence from a specific year or geography above does not prove zero use there either; official statistics only publish names above a minimum threshold.
